APPARATUS FOR LOADlNG OR UNLOADING ARTICLES INTO VESSELS.

SPECIFICATION forming part of Letters Patent No. 582,057, dated May 4, 1897. Application fil d November 27, 1896- $erial No. 613,638- (No model.)

To to whom it may concern: upon the spar-deck A toone side of the hatch- Be it known that I, BEVERLY .I. HARRIS, a way A". This frame may be of any suitable citizen of the United States, residing at New construction sufficiently strong to stand the Orleans, in the parish of Orleans and State of necessary strain thereon and sufficiently light Louisiana, have invented certain new and tohe readily moved-about When necessary.

A pair of arms E are hung at their inner ends, as at E by means of hooks or eyes, to brackets e on the frame C, so as to swing at their outer ends in a vertical plane, and have journaled in their outer ends a cross-shaft E, upon which is mounted a pair of sprocketwheels E over which sprocket-wheels the chains D of the endless carrier D run, as seen most clearly in Fig. 2.

A pair of davits F are mounted upon the frame 0 by means of brackets F, and ropes R, reeving through pulley-blocks P on said davits and other pulley-blocks P on said swinging arm, are used for raising and lowering the outer ends of said swinging arms to meet requirements and for supporting said swinging arms in the required position. Cleats R are provided for theattachment of the ends of the ropes R. If desired, however, a Windlass or capstan may be provided upon the frame 0, to which the ropes Rinay be led and Wound up or paid out, as desired.

The swinging arms E are of sufficient length to extend over into the barge or above the dock from which or to which the articles are being loaded or unloaded, and as the vessel rises and falls relative to the barge or deck the inclination of the height of the outer ends of the arms E may be varied, as above described.

A frame H is located in the hold of the vessel or in any place between decks convenient to the cargo, and a cross-shaft II is j ournaled in this frame and has mounted thereon a pair of sprocket-wheels H over which the chains D of the endless carrier run, as seen in Fig. 1.

A platform I may be provided to receive the articles from the carrier in loading the vessel or to facilitate their being placed upon the carrier in unloading.

Any suitable means may be provided for anchoring the frame H and the frame 0 in position when in use.

It is obvious that if it becomes necessary to shorten the length of the carrier or to increase the length thereof to adjust the same to the distance between the frames H and O in the former case the length may be shortened by removing the links of the carrierchain between successive cross-rods and connecting the terminal links together and the canvas pocket removed and the ends of the canvas sewed together again. When it is desired to lengthen the carrier, links are added and as many extra canvas pockets as necessary.

It will be seen that the flexibility of the canvas of which the apron is composed will allow the pockets thereon to sag in such a manner as to retain the article therein even when any portion of the carrier is running in a direction almost perpendicular, a sufficient length of canvas first having been left between each pair of cross-rods to form a pocket deep enough to contain the articles to be carried thereon.

While I have described and shown my apparatus as used upon a vessel, I do not wish to limit myself to such use, as it will be obvious that a similar apparatus might be used with advantage in storehouses, factories, and in many other connections with little or no modification.

When not in use, the swinging arms may be unshipped at their inner ends and may be drawn up and stored alongside of the frame 0 out of the way.

The frame 0 maybe stationary, but should preferablybe movable, so as to be used upon either side of the vessel, as should also the frame 11, which latter should be light enough to be moved about and used either in the hold or upon one of the decks.

It will thus be seen that I provide an apparatus whereby various articles, and especially fruit, maybe conveniently and quickly loaded into or unloaded from a vessel without injury, such as is apt to ensue from the rough handling ordinarily given to a ships cargo.

Iiavin g thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
